Even if it is fresh install from newly formatted pc, I saw it in the logs. But I don't know when it was occur. I just saw it in the avast logs every time I checked the logs. Is it possible that Automatic rootkit scan will started if the pc is idle, or some sort of scheduled by avast antivirus itself and if you started to use the pc it will not complete to scan?

look, it's hardly possible to troubleshoot this as a running Avast 4.8 is needed to help you, and as said not many are still running Avast 4. Why don't you upgrade to Avast 5 as suggested?

Because I don't think avast 5 stable already. I'll get if it is stable. I don't want my system getting fucked up and ended with formatting the hard drive again. Because I don't have a back up with my files, games, and other application. Therefore I make sure that all things i'll put in pc is fine and don't have any irregularities. Because if I back up my files, games, and other application, I'll be needed another hard drive because it is huge as of now, and it will cost me extra money and I can't afford it because i am just poor.

Build 5.0.545 has been stable for quite some time and works MUCH better than 4.0 and is much quicker. Many of us have vital things on our PC's. But I'm in agreement with Logos and many others here that a clean install of Avast to 5.0.545 would be the best thing for you to resolve your problems.

Hi the invulnerable, I moved to Avast 2 months ago and I can honestlysay that it has been a flawless ride. You should take the advice givento you by everybody that has answer on this thread and move on toAvast5. Before I moved to Avast I was a little bit restless because ofwhat I had read but I am a gambling man and I am happy that I took achance. Do yourself a favor and do the upgrade.Bo
